Insecticide $\rightarrow III$. $Na_3AsO_3$ (Sodium arsenite is used as an insecticide).$B$. $K_2Cr_2O_7 / 50\% H_2SO_4$ $\rightarrow I$. $COD$ (This mixture is used to determine the Chemical Oxygen Demand).$C$. Bleaching of clothes and paper $\rightarrow V$. $H_2O_2$ (Hydrogen peroxide is a common bleaching agent).$D$.
